== Version 4 release notes ==

The main change in this version is the inclusion of a plugin architecture.  This allows end users to write there own additions to the program and load them at runtime. For more information see the [wiki:plugin PlugIn] page.

Some example plugins are supplied in the jar file:

 * http://users.aber.ac.uk/bpt/jpsychomorph/version4/pluginexamples.jar -- example compiled plugins

The examples include symmetrising, chimeric transforms, colour calibration and enhancing / repairing templates.  To enable these you need to download the jar file and load the plugins at runtime.  They should be automatically reloaded on future runs from the same machine, provided they haven't been moved or deleted.

Other changes include adding some more options from the Tcl/Tk-C++ version, such as different warping options, different wavelet filter options, overlap control (to stop warping "folding") and some additional work on the ORASM (and similar) feature detection / tracking.
